(The day before yesterday and yesterday I had a, well, lively
conversation regarding this macro. The interesting bits start at
https://lkml.org/lkml/2015/6/17/383 . Let's see how things go here.)

As I understand it, this alias is only useful if there's a corresponding
struct platform_device, somewhere. Ie, this alias implies a
platform_device that will fire of a "MODALIAS=platform:atmel_flexcom"
uevent when it's created. That would be a platform_device using a
"atmel_flexcom" name.

If that's correct, then I think this MODULE_ALIAS macro isn't needed
here, as I couldn't find a platform_device using that name. (But perhaps
a patch that adds it is pending, somewhere.)

Thanks,


Paul Bolle
